also generates organic wastes which are generally dumped. On the other hand many people felt shortage of animal dung for biogas production. This study is an attempt to find out the way between these situations by finding the suitability of kitchen wastes addition for biogas production. The experiment was performed in 5 L glass bottles with two treatments i.e. buffalo dung alone and mixture of dung with kitchen wastes. The bottles were filled on daily feeding basis by the feeding material at 5.3% total solids for the experimentation period of 80 days. On first day 12 mL fresh digested biogas slurry from running biogas plant was also added in all the digesters as inoculum. Daily biogas production was measured by water displacement method. Results show that co-digestion of dung and kitchen wastes produces 85.71 to 195.12% higher biogas than dung alone. Overall it produces 2.69% higher total biogas for the experimentation period of 80 days.
